■ Intra frame period

Determine how often to plant an I frame� The shorter the duration, the more likely you will get better video quality, but at the cost of higher network bandwidth consumption� Select the intra frame period from the following durations: 1/4 second, 1/2 second, 1 second, 2 seconds, 3 seconds, and 4 seconds�

■ Video quality

A complex scene generally produces a larger file size, meaning that higher bandwidth will be needed for data transmission� Therefore, if Constant bit rate is selected, the bandwidth utilization is fixed at a selected level, resulting in mutable video quality performance� The bit rates are selectable at the following rates: 20Kbps, 30Kbps, 40Kbps, 50Kbps, 64Kbps, 128Kbps, 256Kbps, 512Kbps, 768Kbps, 1Mbps, 2Mbps, 3Mbps, 4Mbps, 6Mbps, and 8Mbps� You can also select Customize and manually enter a value�

On the other hand, if Fixed quality is selected, all frames are transmitted with the same quality; bandwidth utilization is therefore unpredictable� The video quality can be adjusted to the following settings: Medium, Standard, Good, Detailed, and Excellent� You can also select Customize and manually enter a value�

If JPEG mode is selected, the Network Camera continuously sends JPEG images to the client, producing a moving effect similar to a filmstrip� Every single JPEG image transmitted guarantees the same image quality, which in turn comes at the expense of variable bandwidth usage� Because the media contents are a combination of JPEG images, no audio data is transmitted to the client� There are three parameters provided in MJPEG mode to control the video performance:

■ Frame size

You can set up different video resolution for different viewing devices� For example, set a smaller frame size and lower bit rate for remote viewing on mobile phones and a larger video size and a higher bit rate for live viewing on web browsers� Note that a larger frame size takes up more bandwidth�

■ Maximum frame rate

This limits the maximum refresh frame rate per second� Set the frame rate higher for smoother video quality�

If the power line frequency is set to 50Hz, the frame rates are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, and 25fps� If the power line frequency is set to 60Hz, the frame rates are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, 25fps, and 30fps� You can also select Customize and manually enter a value� The frame rate will decrease if you select a higher resolution�

■ Video quality

The video quality can be adjusted to the following settings: Medium, Standard, Good, Detailed, and Excellent� You can also select Customize and manually enter a value�

NOTE:

►Video quality and fixed quality refers to the compression rate, so a lower value will produce higher quality�

►Converting high-quality video may significantly increase the CPU loading, and you may encounter streaming disconnection or video loss while capturing a complicated scene� In the event of occurance, we suggest you customize a lower video resolution or reduce the frame rate to obtain smooth video�

IP8352 specifications

The Vivotek IP8352 is a versatile and high-performing network camera designed for a range of surveillance applications. With its sleek and compact design, it caters to both indoor and outdoor installations, making it a popular choice for businesses and homeowners alike.

One of the standout features of the IP8352 is its exceptional image quality. Equipped with a 2-megapixel sensor, it delivers high-definition video at resolutions up to 1920x1080 pixels. This ensures clear and detailed images, even in challenging lighting conditions. The camera also supports WDR (Wide Dynamic Range) technology, enabling it to capture balanced images in scenes with both bright and dark areas.

The IP8352 boasts an advanced IR-cut filter which allows it to capture clear images both day and night. With built-in IR illuminators, the camera can deliver black and white video up to 30 meters at night, providing continuous surveillance even in complete darkness.

Another impressive characteristic is the camera’s ability to provide real-time video streaming. It supports multiple video compression formats, including H.264 and MJPEG, facilitating efficient bandwidth usage without compromising quality. This feature is essential for systems where network resources are limited, allowing users to adjust the streaming settings based on their needs.

The Vivotek IP8352 is also equipped with Smart Stream technology, which optimizes bandwidth efficiency by allowing users to prioritize specific regions within the camera's field of view. This means that critical areas can be monitored more closely while other less important sections can use lower resolution, saving on storage and bandwidth.

Additionally, the camera features an IP66-rated housing, ensuring that it is dust-tight and capable of withstanding heavy rain and harsh environmental conditions. This durability makes it suitable for various applications, from retail stores to warehouses and outdoor settings.

In terms of installation, the IP8352 supports Power over Ethernet (PoE), simplifying the installation process by allowing both power and data to be delivered through a single cable.

Overall, the Vivotek IP8352 combines high-definition video quality, advanced surveillance technologies, and robust construction, making it a highly effective solution for modern security needs. Its flexibility and features make it an ideal choice for enhancing security in diverse environments.
